Embodiment Construction

[0021] Hereinafter, preferred embodiments according to the present invention will be described.

[0022] The new energy key power electronic components used in electric vehicles mainly include DC / DC, motor controller, high-voltage distribution box, vehicle controller VCU, etc., such as figure 1 shown. And these key components are mainly assembled in the front compartment 6 of the electric vehicle, such as figure 2 shown. Due to the limited space of the front cabin 6, too many parts will lead to relatively complicated assembly process, interference in motion, difficulty in heat dissipation, high cost, difficult maintenance and reduced safety. Therefore, the unified design and integration of various hardware circuit boards enhances the reliability of the system, removes unnecessary board-level connections, removes redundant component shells, reduces weight and volume, and saves costs.

[0023] Such as figure 2 and image 3 As shown, the electric vehicle power control syst...

Abstract

The invention provides an electric automobile power control system integrated device. A method of integrated design is utilized, in an automobile front cabin, the power control system integrated device includes a first arrangement area and a second arrangement area which are used for arrangement of different power electronic parts of an electric automobile. At the same time, the power control system integrated device provides integrated water cooling used for cooling large-power power electronic devices. The device effectively solves the problem that since numerous modules are integrated, the EMC is difficult to achieve, greatly improves stability and reliability of the power electronic parts, and improves convenience of maintaining the parts.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to an integrated device for a power control system of an electric vehicle. Background technique [0002] The space in the front compartment of electric vehicles is limited. At the same time, compared with traditional gasoline locomotives, there are more special parts for electric vehicles, which mainly include DC / DC, motor controllers, high-voltage power distribution boxes, and vehicle controller VCUs. These components are basically They are all arranged in the front cabin, which poses a great challenge to the space requirement. The arrangement of these components is not only related to the realization of the functions of each component, but also related to the performance of the electric vehicle, such as the electromagnetic interference of electronic and electrical components. The distance of each component, the electromagnetic protection of high voltage, motion interference, hi...
